6 dbadm_sudo_selinux - Security Enhanced Linux Policy for the dbadm_sudo
7 processes
8
10 Security-Enhanced Linux secures the dbadm_sudo processes via flexible
11 mandatory access control.
12
13 The dbadm_sudo processes execute with the dbadm_sudo_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dbadm_sudo_t
20
21
22
24 The dbadm_sudo_t SELinux type can be entered via the sudo_exec_t file
25 type.
26
27 The default entrypoint paths for the dbadm_sudo_t domain are the fol‐
28 lowing:
29
30 /usr/bin/sudo(edit)?
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 dbadm_sudo policy is very flexible allowing users to setup their
40 dbadm_sudo processes in as secure a method as possible.
41
42 The following process types are defined for dbadm_sudo:
43
44 dbadm_sudo_t
45
46 Note: semanage permissive -a dbadm_sudo_t can be used to make the
47 process type dbadm_sudo_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 dbadm_sudo policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dbadm_sudo with the tightest
56 access possible.
